gyroelongated pentagonal bicupola
In geometry, the gyroelongated pentagonal bicupola is one of the Johnson solids (''J''46). As the name suggests, it can be constructed by gyroelongating a pentagonal bicupola (''J''30 or ''J''31) by inserting a decagonal antiprism between its congruent halves.
The gyroelongated pentagonal bicupola is one of five Johnson solids which are chiral, meaning that they have a "left-handed" and a "right-handed" form. In the illustration to the right, each square face on the bottom half of the figure is connected by a path of two triangular faces to a square face above it and to the right. In the figure of opposite chirality (the mirror image of the illustrated figure), each bottom square would be connected to a square face above it and to the left. The two chiral forms of ''J''46 are not considered different Johnson solids.
